IMPROVEMENT IN ENVELO PES.

Speclcaton forming part of Letters Patent No. 84,840, (lated December 8, 1868; antcdated November 30, 1868.

To all whom t may concern:

Be it known that I, CHARLES R. M. POHL, of the city of Richmond,'in the county of Henrico and State of Virginia, have invented a new and Improved Mode of Constructing a Paper Envelope, to be called The Double- Seal Envelope. The principal part in the construction is the combination of two seals into one, by which process the envelope is connected in its differentparts and securely sealed up in the same time; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference thereon.

I will now proceed to describe its construction and operation.

Figure 1 represents the paper cut into the shaperequired for making the envelope, of any size. The red marking represents the gum on the seal, and this is the only part where gum is applied. The blue marks represent cuts in the paper.

Letter X is the inside of the front part. Letter a is the left wing. Letter b is the right wing. Letters c o are the connecting seal. Letter l is the seal-flap. Letter e is the closing-Hap. Notches are cut on both seals.

Operation.

First, take the ready-cut paper, as represented in Fi g. l, lay down the right wing b to the inside of the front part, X, and lay back the half connecting-seal c. (See Fig. 2.)

Second, lay down the left wing a to the inside of the front part, X, and lay back the half connecting-seal c, so that the two half-seals join into one whole. (See Fig. 3.)-

Third, raise the two half connecting-seals c c with your right hand, and put both through the cut in the closing flap. Smooth both down, so that they join well into one seal. (See Fig. 4, representing the envelope ready for use.)

Fourth, meisten the gum on the sealdiap well, and smooth the seal down, covering the connecting-seal c c. This done, the envelope is securely closed. (See Fig. 5.)

That I claim as my invention, and desire to secure by Letters Patent, is

The closing of the envelope by the action of the double seal, substantially as described.

CHARLES R. M. POHL.
